Pls is it possible to get a glimpse of the 2009 and 2011 past question?

Though it's similar to 2009 but it isn't it because it has mass hung on it, and there's no logarithm. 2012, Q3, is real but the some answers on the past questn booklet r wrong.

2011 sir and not 2012

ibroh22:

how do I call u then?, thought you said you are going to give me your number,so I can call you,thats why I send you my mail if you don't want to drop the number on the thread

ibroh22:
2011 sir and not 2012

Sorry, It's 2011, for Q3.

Then it means the set up will not be having a mass hung on it but it's still a BIFILAR SUSPENSION. So, we are safe to assume that it will go through the same process as that of 2009 excluding the mass attached. And if i may ask, how do you know this will be including logarithm?


If you have anything to give, give it and stop taking life too serious

NatureBoy91:
not my number but u can reach me through: 07080241889

thanks so much sir,,,,I really appreciate the insight,i will work on all wat u told me

Yes, but they will start from 80.0cm to 40.0cm. U will evaluate LogL & LogT

STUDY in RUSSIA,UKRAINE,BELARUS and GEORGIA. Contact me on 07030285286

NatureBoy91:
U are welcome

one more question sir,,, sorry for the question,are we going to be stirring the salt solution continuously till we take our readings or we stir once and leave it till we take our readings after the stipulated time

U stir continuously but take readings in every 2 minutes or u watch when it boils(bubbles at the surface of the liquid).

thanks sir

we jst did the 2009 question at school today, but am having difficulties plotting d graph cause dae said tsqaure against H.and my slop was quite different from what dae ave in d past question

Please for question number 1, the time t is for how many oscillations 10 or 20

check the question well,is it H against T square or T square against Hi think it's H against T square cos d slope will have dis unit..cm/sec square

d slope doesn't ave any unit I got 0.039. approximately 0.04 dre is no unit in slope

Please sirs which year's question should i check for question 1, 2 and 3

no 1 is bifilar pendulum. is two ways experiment. one d length of the thread could be kept constant like 60cm while d distance varies from 90cm n 10cm, 85cm to 15cm on the meter rule n to oscillate for 20. 2. distance is kept constant while the length is adjusted from 95cm n 5cm. Is hard abit to perform.
no2. is abt impurities in a liquid. when u boil water on a beaker u av to weigh salt 50g. wen d water boils u read d boiling point of the water n record it. den add 50g of salt n it will increase d boiling point of water from 100c. wen it boil u add another 50g making it 100g. u repeat it till 250g of water. subtract b1-bo to V ur temperature.
No3. is potentiometer using bulb in place of resistor.
good luck

there is unit in slope sir,dont make that mistake,it depends on the unit of the parameters you are plotting,,,if u are plotting two parameters of same unit,the slope will not have unit,but if you are plotting a graph in which the parameters are of different unit,it will have unit depending on the unit,check the series and see the answer they got for slope for different years,u will see what am talking about

U won't be asked of that but will be asked similar to that experiment.

2009 is similar to Q1, 2011 for Q3

Nature boy, is dre a formular for manipulating readings after doing like 40cm and 60cm can I manipulate d rest

note question one can be related from T = 2Π√{l/g} if you re arrange u get T = 2Π/√g L^0.5 take k = 2Π/√g T = k L^0.5 take log of both sides log T = log k + log L^0.5 log T = log k + 0.5log L comparing with y = MX + c y= log T , x = log L c = intercept = log k from here we can deduce our slope to be in the range of 0.5 to 0.3

hey bro, don't knw if u cud help wit d experiment values so DAT I can use it to teach my people...where am serving dere is no tools to carry out this experiment u can message me on WhatsAp or drop yha contact....anyone dat suit u..we b expecting sir
